Same as I said before - she needs to find out how she responds to it. Start out at 5 mg for a week or two, build up to 10 for a while. If she isn't getting any acne or doesn't feel like she's seeing results after a couple weels by that dose, increase another 5, check the results & sides and increase again if needed. Also check the brand as some are known to be underdosed. She should really start seeing some sort of sides around 10 mg, but it depends. Can run 8-12 weeks, or longer if she wants. Again based on results, dosage, cost, etc. For a person who isn't competing on a schedule, there's just no reason to push the envelope. Low & slow. Sure she can try that cycle, but start slow & build up the dose (or cut back as needed) and for how ever long, but the usual cycle is around 8+ weeks.
